What Is Bug CLI?

Bug CLI is the AI-powered security testing platform I built as my personal research tool. Think Burp Suite Pro meets Claude AI.

Why I'm Keeping It Private

  • Liability: Security tools carry legal risks I'm not prepared to assume
  • Focus: I'd rather hunt bugs than provide software support
  • Advantage: This is my competitive edge in bug bounty programs

But I'll document everything about how it works, what I learned building it, and the results it produces.

What It Does

๐Ÿ”

HTTP Interception

Full request/response capture and analysis

๐Ÿค–

AI Explorer

Conversational security testing with Claude

๐Ÿ•ท๏ธ

Web Crawler

Automatic site mapping and discovery

๐Ÿ’‰

Smart Fuzzing

4 attack types: sniper, battering ram, pitchfork, cluster bomb

๐Ÿ”

Vulnerability Scanning

Passive and active security testing

๐Ÿ“Š

Smart Decoder

URL, Base64, JWT, hashing - AI-powered

And 14+ more modules I've built as I learned...

See It In Action

I'll be showing Bug CLI in videos once my YouTube channel launches:

  • How I use it to solve PortSwigger labs
  • Real reconnaissance workflows
  • AI conversations during testing
  • Vulnerability discovery processes

You'll understand the concepts, see the methodology, and learn how AI can augment security testing - even if you can't download my specific implementation.

What I Learned Building It

HTTP IS EVERYTHING

Building the proxy forced me to understand HTTP at a deep level. Headers, methods, status codes, cookies, sessions - you can't build interception without understanding the protocol.

AI NEEDS STRUCTURE

Raw LLM prompts aren't enough. I had to build specialized agents with specific tools, context, and workflows. The Claude Agent SDK was crucial here.

SECURITY TOOLS ARE COMPLEX

Burp Suite charges $475/year for good reason. Handling edge cases, managing state, preventing false positives - it's legitimately hard engineering.

THE ARCHITECT METHOD EMERGED NATURALLY

Building Bug CLI required me to think architecturally: design the system, then have AI help implement it. This became my learning method.

Built With

Language: Python 3.9+
AI: Claude Haiku 4.5 via Anthropic API
Framework: Claude Agent SDK
Interface: Rich TUI with prompt_toolkit
Database: SQLite with async support
Browser: Playwright for automation
